HOLDER FOR FINGER-RINGS.

SPECIFICATION forming part of Letters Patent No. 407,668, dated July 23,1889.

Application filed March 1, 1389. Serial No. 301,657. (No model.)

To aZZ whom, it may concern:

Be it known that I, CHARLES A. KRON, of New York city, New York, have invented an Improved Holder for Finger-Rings, of which the following is a specification.

This invention relates to an improved holder or catch for a display-tray or for a case or box that is to hold one or more finger-rings. The holder is so constructed that by a partial revolution of one of its plates the ring may be locked, while by a reverse motion it will be released.

The invention consists in the various features of improvement, more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a top view of a case provided with my improved holder. Figs. 2 and 3 are bottom views of the holder, showing it in different positions. Fig. 4 is a face view of the lower plate a; Fig.

5, a similar view of upper plate I), and Fig. 6

more fully shown in Fig. et-that is, it has a circular opening at the center, which is traversed by preferably two horns a, projecting partially across it from opposite v directions. Around the circular opening there is a subdivided circular slot o The inner rim a of the circle is connected to the body of plate a by preferably three radial arms a ,traversing slot 0 Upon the plate a there is placed the upper movable plate b. This plate has a rectangular central slot Z). At its edge it has preferably three down wardly-proj ecting pron gs b These are passed through the slot a and are then bent over, one prong passing through each subdivision of said slot. Thusit will be seen that the plate I) may be revolved upon plate a, but that its motion will be limited by the pron b striking the arms a In use the plate b is revolved until its slot b is brought directly in line between the horns a, Fig. 2. A finger-ring 15 is then passed through the slot and between the horns. By rotating the ring ninety degrees the plate I) is brought into the position shown in Fig. 3, in which the slot b stands at right angles to the horns. In this position the horns traverse the opening within the ring B, and thus securely lock the ring in place. To release the ring it is only necessary to revolve it in the reverse direction until the Darts again arrive in the position shown in Fig. 2. The slot (L in connection with the engaging prongs b properly centers the plate I) and prevents any lateral motion of the plate.

\Vhat I claim is- 1. The combination of plate a, having an opening that is traversed by a horn projecting partially across the opening, with a slotted plate 1), adapted to be revolved above plate a, substantially as specified.

2. The combination of fixed plate a, having a central opening traversed by a horn, and a surrounding slot a traversed by radial arms, with a superposed movable plate I), having a central slot, and prongs b that e11- gage the slot a of plate a, substantially as specified.

CHARLES A. KRON.
